Genetic Polymorphism of ADA in Taiwan Aboriginal Populations--New ADA Variants Detected by Isoelectric Focusing Method
ADA subtype polymorphism in nine aboriginal populations (Gaoshan) of Taiwan was studied by means of the IEF method. A new ADA variant allele, ADA<sup>*</sup>Taiwan1, was in a high allele frequency in two Gaoshan populations, the Amis and the Paiwans. Another new variant, ADA<sup>*</sup>Taiwan2, was found in only one case of heterozygote in the Saisiats. Allele frequencies of a common allele, ADA<sup>*</sup>2, in the Paiwans and the Amis were the highest among the Asian populations so far studied.
